I am so proud of Rypel Lab alum Lauren Hitt for publishing this important paper in Ecosphere on Putah Creek salmon natality: esajournals.onlinelibrary.wiley.com/doi/10.1002/... A press release was also published by @ucdavis.bsky.social on it this morning www.ucdavis.edu/climate/news...

New paper out! An analysis of recent advances and challenges in tag miniaturization. I had a good time drawing Figure 3 (see below). Small things can help ensure the tagged animals recover fully!

Coho are typically thought to rear in their natal habitat for a year before migrating to sea. We found that many fish (44%) leave their natal habitat early and spend several months rearing in the lower portion of the creek before emigrating. (3/8)

Which exploitation strategy should be adopted for salmonid metapopulations? 🎣 Could knowledge of source-sink dynamics improve their management? Our latest paper is just out! onlinelibrary.wiley.com/doi/10.1111/... Simulations results 📈 suggest being not selective as the best strategy 💡

What happens to small streams during a hurricane? Here are time-lapse photos (every 15 min) from our Flow Photos Explorer of 3 sites in PA during Helene. Shocking how high they get and that any fish can survive. They are so flashy, we might even have missed the peak. [gif by Phillip Goodling]

The status of European eel remains critical. ICES advises that there should be zero catches of eel in all habitats in 2025. Further, that all non-fisheries related anthropogenic mortalities should be zero @icesmarine.bsky.social ICES advice available at ices-library.figshare.com/articles/rep...
